title: Long-term survival after repetitive surgery for malignant hemangiopericytoma of the lung with subsequent systemic metastases: case report and review of the literature.
abstract: Malignant hemangiopericytoma represent less than 1% of all vascular and about 5% of all sarcomatous tumors. We are reporting the uncommon clinical case of primary pulmonary localization, of which approximately 100 cases have been published in the literature. A 54-year-old male underwent left upper lobectomy seven years ago for a tumor which proved to be a malignant hemangiopericytoma. Six months later a metastasis in the abdominal wall in the epigastrium appeared and was completely excised without further treatment. During a follow-up of 16 months another metastasis developed in the mesenterium causing ileus and leading to laparotomy with resection of 120 cm small bowel. After this procedure followed by two cycles of chemotherapy the patient remained free of disease. Details of the clinical course and a review of the literature are presented.
